Communication service system

Abstract

A communication service system includes a SNS server 1 that manages contents, and client terminals 10 to 30 that can make access to the SNS server 1 via a network 40. Each of the client terminals 10 to 30 includes a portion with which the client terminal can obtain an object. The SNS server 1 manages objects input by the client terminals 10 to 30, and allows a plurality of client terminals that are connected to the network 40 and browse the same content to share objects.
